Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed April 28, 1910. Serial No. 558,168.

To all whom it may concern:

Be it known that I, EUGENE SIMEON, engineer, a citizenof the Republic of France, and resident of Grenoble, Isere, France, have invented a new and useful Improvement in Machines for Stretching Tawed Hides and Chrome Tanned and Colored Hides or Skins, which improvements are fully set forth in the following specification.

This invention relates to the stretching of hides'of all sizes and kinds.

I The stretching comprises two operations: stretching the body of the hide and finish ing the edges. The stretching of the body consists in drawing the hide, which has been hardened by the tawing process, in order to obtain the greatest possible length and width. The finishing of the edges consists in especially drawing out the edges of the skin, which have not been touched by the first operation. The combination ofthese two operations has the effect to draw out the skin in all directions, in length, in width and all over its surface, in the middle as well as on its edges, so as to give the skin the greatest pliability, while retaining its natural shape. This result is obtained in the present invention by means of the machine described farther on, which carries blades of difierent forms, curved or rectangular, according to whether the body or the edges are to be stretched.

In the accompanying drawings Figure l is a front elevational view showing the machine in its entirety; Fig. 2 is a side elevation, the machine being shown from the left side; Fig. 3 is a plan View, the upper part supposed to have been removed; Fig. 4 is a plan View of the device to carry the hide by an endless belt; Fig. 5 is a side elevation of the drum with the blades for stretching the skin; Fig. 6 is a detailed view of the blades of the drum for stretching the hide; Fig. 7-

is a side elevation of the drum for the edges; Fig. 8 is a detailed View of the blades for the stretching of the edges; Fig. 9 shows the position of the knives on the drum.

Drum 1 of the machine, fixed upon axle 3, carries on its circumference a certain number of blades, 4 or 6, which are absolutely rigidly attached. They are placed one behind the other, without overlapping each other in fan shape, (Fig. 9) that is they form a certain number of segments in which one blade is parallel to the generating line,

while the others, on the right and left, are more or less inclined. The blades are either curved or rectangular and are provided with dull edges so that they do not cut.

A frame 7 carries the axle and all the controlling and transmitting parts which give the drum 1 the desired rotary movement. A table 8 is carried by the upper part of the frame 7. This table is provided with guards 9 near the drum. In a bearing of the frame 7 rotates the shaft 11 which is more or less directly driven by a motor. A transmission by means of a belt 12 and pulleys 13 and 14: or any other suitable transmission device, imparts a rotary movement to an intermediate shaft 15, which transmits this movement to shaft 3 of the drum by means of belts and pulleys suitably arranged or by any other suitable transmission device. Since drum 1 must have an alternating ver tical movement, its axle 3, guided in the slides 16, of the frame 7, is also fastened by means of a forked rod 16 to a crank 17 on shaft 11. It is well understood that, in order to allow such movement, the slides 16 are curved and form an arc of a circle having a radius equal to the distance between 15 and 3.

The stretching (of body and edge) is obtained by helping the hides held against drum 1 by the two hands of the operator and by the pressure of his body against the table. The hands turn in succession all parts of the hide toward the moving blades. In order to ease the work of the operator, an endless belt of leather or felt can be employed for holding and pressing the hide in position. This belt 21 is mounted on the rollers 20, 20', 20", the axles of which are carried by a frame 18, pivotally mounted on 19, the axle of roller 20. The frame 18 is preferably provided with a three armed strengthening member 18, in order to render the frame absolutely rigid. On this same axle is mounted pulley 22, rigidly connected with roller 20 and which is connected by belt 23 to pulley 2 1 keyed upon shaft 15. The felt or leather belt 21 can, at the will of the operator, be brought in contact with drum 1 by means of a pedal 25 which acts upon rod 26 through a spring 28. The rod 26 influences arm 27, rigidly connected to frame 18, mounted on 19. The nature of the felt or leather belt 21 and the elasticity of spring 28 allows said felt or leather belt to accom- 119 modate itself to all positions taken drum 1.

scribed is not in any way restrictive, because all other devices regarding the arrangement of the blades and the functions of the drum which form, in conjunction with the device to bring the hides on the drum, the essential characteristics of the invention, are also comprised therein.

IVhat I claim is:

1. In a device of the class described, in combination, a frame, a driven shaft, an auxiliary shaft driven by said first mentioned shaft, a rotatable drum driven from said auxiliary shaft, said frame being provided with arc-shaped guides supporting said drum, each of said guides forming an arc of a circle, the center of which is said auxiliary shaft, and means for reciprocating said drum upon said guides.

2. In a device of the class described, in combination, a frame, a driven shaft, an auxiliary shaft driven by said first mentioned shaft, a rotatable drum driven from said auxiliary shaft, said frame being provided with arc-shaped guides supporting said drum, each of said guides forming an arc of a circle, the center of which is said auxiliary shaft, said first mentioned shaftbeing provided with a crank, and connecting means between said crank and said drum for reciprocating the latter upon said guides.

3. In a device of the class described, a frame provided with guides, a drum rotatably supported in said guides, means to rotate said drum continuously in one direction, and means to reciprocate said drum upon said guides, said means comprising a rotatable shaft provided with a crank, and a The machine which has been herein de-.

connecting rod interposed between said crank and said drum.

4:. Ina device of the class described, a frame provided with arc-shaped guides, a drum rotatably supported in said guides, means to rotate said drum continuously in one direction, and means to reciprocate said drum upon said guides, said means comprising a rotatable shaft provided with a crank, and a connecting rod interposed between said crank and said drum.

5. In a device of the class described, in combination, a main frame, a drum rotatably mounted thereon, means for rotating said drum, means for simultaneously reciprocating said drum, an auxiliary frame pivotally mounted onsaid main frame, an endless belt carried thereby, means for driving said belt, and means for moving said auxiliary frame to cause said belt to move into and out of engagement with said drum.

6. In a device of the class described, in combination, a main frame, a drum rotatably mounted thereon, means for rotating said drum, means for simultaneously reciprocating said drum, an auxiliary frame pivotally mounted on said main frame, a plurality of pulleys rotatably mounted in said auxiliary frame, an endless belt carried by said pulleys, means for driving said belt, and means for moving said auxiliary frame to cause said belt to move into and out of engagement with said drum.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

EUGENE SIMEON.
